When I received the product, probably the first thing I noticed was the ergonomic grip for holding; which is always a bonus with liquid eyeliner, and a plus in my books. I of course made some lines on the back of my hand to check the formula and it seemed all okay. Now, creating winged looks is no challenge for me, I've been doing it for years, and was excited to see how thin I could go - as I tend to do more subtle wings these days - but alas...I couldn't get much product off the very end of the tip, only the fatter part of the brush end. I tried and tried, but it felt so incredibly dry and difficult to run a thin, solid, line over my lids. In all fairness, I have huge eyelids and they do have a bit of skin to get through, but it seemed the formula only wanted to come off parts of the brush/end, rather than apply in a fluid motion that liquid liner typically does.
The formula itself is actually fine, what I did manage to get on, didn't budge after being applied and lasted the entire night.
I am going to give them the benefit of the doubt and hope that perhaps I just got a dud, but when I consider the price point and what else is on the market, this product failed to differentiate itself. When I ask myself if I would be happy to pay for this product, or would I repurchase? No, not really.
It did what it said - an intense sweeping line in one stroke with a felt-tip eyeliner and its grip zone hold. But during my review of this eyeliner, I resisted myself to yawn because every "Watery" feeling around my eyes, this started smudging straight away! I would expect an eyeliner to be at least waterproof but this just was not. If you apply eyeliner away from the root of your eyelashes - or have dry eyes, this might work. For everyone else - especially for someone like me, who wears contact lenses, this is not for you. It might work if you want to practice at home - but don't try wearing this and send your evening..
Tips: If your tip gets dry, try "wiping" the end with a wet tissue - the link will come back :)
